Lunt LS230THa/B3400 Double Stack: Advanced solar telescope

The Lunt LS230THa/B3400 Double Stack is much more than a solar telescope: it's a work of optical engineering dedicated to exploring the Sun in minute detail. With its impressive 230 mm aperture, Double Stack system and B3400 blocking filter, this telescope offers an unrivalled observation and imaging experience. Designed for the most demanding solar astronomers, this state-of-the-art instrument reveals the complex dynamics of our star with exceptional precision and contrast.

Revolutionary technology to explore the Sun

The LS230THa is based on an advanced system of internal Fabry-Perot standards, which exploit the wave-like properties of light to isolate the H-alpha line (656.28 nm). In Double Stack mode, two internal standards reduce the bandwidth to < 0.5 Å, offering spectacular contrast. This setting reveals subtle, dynamic structures such as :

  • Solar protuberances: Gushing thousands of kilometers into space.
  • Dark filaments : Real rivers of plasma suspended above the surface.
  • Chromospheric granulation : Drawing the fine texture of the Sun.

The barometric pressure control system, the Pressure TunerThis electronically-controlled system guarantees a uniform image across the entire field, compensating for atmospheric or thermal variations.

Incomparable technical features

  • Opening : 230 mm (without central obstruction), offering exceptional brightness and resolution.
  • Focal length : 1610 mm (f/7), ideal for combining high resolution with a moderate field of view.
  • Double Stack: Two internal standards optimized to reduce bandwidth to < 0.5 Å.
  • B3400 blocking filter : With a generous 34 mm diameter, it is designed for advanced imaging with large-format sensors, guaranteeing a vignetting-free field of view.
  • Pressure Tuner electronic system : Precise control via an electronic module for smooth, consistent adjustments.
  • Feather Touch focus: The legendary Starlight Instruments focuser with 10:1 reduction offers unrivalled precision for ultra-fine adjustments.
  • Robust construction: Carefully machined aluminum tube, designed to last and withstand intensive use.

Why choose the LS230THa/B3400?

  • An unprecedented opening in solar observation: At 230 mm, this telescope captures an exceptional amount of light, enabling us to observe details invisible with smaller instruments.
  • Exceptional contrast thanks to Double Stack : Bandwidth reduced to < 0.5 Å reveals the fine, dynamic structures of the Sun as never before.
  • Advanced imaging with the B3400 : The B3400 blocking filter is optimized for large astrophotographic cameras, guaranteeing sharp images across the entire field.
  • Pressure Tuner technology : Easily adjust barometric pressure for a perfectly uniform image, even in changing conditions.
  • Ultimate optical precision : Thanks to the Feather Touch focuser and IR-coated optical components, every detail is captured with exceptional sharpness.

Recommended applications

  • Advanced visual observation : Explore solar protuberances and filaments with unrivalled contrast.
  • Professional astrophotography : Capture spectacular high-resolution images of the Sun thanks to compatibility with large-format sensors.
  • Solar scientific research : Ideal for analyzing dynamic solar phenomena such as coronal mass ejections (CMEs) and magnetic variations.
